Quality Control

Our 3'-Methyl-Biphenyl-3-Carboxylic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring high-purity intermediates for GMP and research purposes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
